-MAA - Low Level Skeleton Library for Communication on Intel platforms
+libmraa - Low Level Skeleton Library for Communication on GNU/Linux platforms
==============
-Library in C/C++ to interface with Galileo & other Intel platforms, in a
-structured and sane API with port nanmes/numbering that match boards & with
-bindings to javascript & python.
+Libmraa is a C/C++ library with bindings to javascript & python to interface
+with the IO on Galileo, Edison & other platforms, with a structured and sane
+API where port names/numbering matches the board that you are on. Use of
+libmraa does not tie you to specific hardware with board detection done at
+runtime you can create portable code that will work across the supported
+platforms.
-The intent is to make it easier for developers and sensor manufacturers to map
+The intent is to make it easier for developers and sensor manufacturers to map
their sensors & actuators on top of supported hardware and to allow control of
low level communication protocol by high level languages & constructs.
## API

+These interfaces allow you to interact with all libmraa functionality. The C++
classes directly wrap the C API and provide a near 1:1 mapping of
functionality.

-### ENV RECOMENDATIONS
+## DEBUGGING
-All of these are 'optional', however they are recommended. Only a C compiler,
-cmake, libm and pthreads are technically required to compile.
-
-- Swig 3.0.1+ built with node.js & python support (0.10.x)
-- doxygen
-- sphinx (requires doxygen)
-- pygments
+Sometimes it just doesn't want to work, let us try and help you, you can file
+issues in github or join us in #mraa on freenode IRC, hang around for a little
+while because we're not necessarily on 24/7, but we'll get back to you! Have a
+glance at our @debugging page too
## COMPILING

## CONTRIBUTING
-Please see the @ref contributing page
+Please see the @ref contributing page, the @ref internals page may also be of
+use.
